Days 2 and 3 POST OP

Day one post op ended with some serious nausea and mild vomiting.  This made me call the surgeon who reassured me this was not uncommon but could be something serious to watch.  He told me to only take in what liquids I could, not to overdo it, but to also stay hydrated if possible.   He then called me in a prescription to help with the nausea.  That did the trick.  Next day, day 2 I was fine.  Day 2 brought some pain still, especially in the area of the port, and plenty of gas pains.  Nothing too terrible though.  Continued with pain meds every 4 hours and took a great walk with my dog.  A little on the slow side, but I'm making great progress I think!!
Day 3 is today.  After the nausea I was really afraid to move off of clear liquids on to full liquids, but I gave it a small try last night with some skim milk.  That went down okay, so today for lunch I tried some cream soup - tomato basil.  I really only had a couple of spoons before I was full... Hubby asked what was wrong and I just explained that nothing was wrong, the soup was delicious, I was handling it okay, I was just full.  Took the dog to the dog park for our walk today,  I didn't last very long, but it was better than nothing.  I'm not having to take pain meds every 4 hours, although still taking them, and I picked up some GasX to help with all the gassy feelings I'm having, but I can't really tell if it's gas or indigestion or what...
